This invention relates to cooling towers and has for its object to produce a spray tower having an elevated louvered bottom of simple and strong construction so made that air may freely pass upwardly therethrough over the entire area of the tower, as it has been found in louvered towers, wind blowing from one direction will be so moisture laden before it has been contacted with the spray on the far side of the tower that practically no cooling by evaporation is effected. The prime object of the invention, therefore, is to insure the entry of unsaturated air throughout the entire body of sprayed water, through the side louvers and also through the bottom of the tower to insure the greatest possible cooling of the liquid spray, in combination with a water spray system which is depended upon to break up the water in very line particles, rather than using baiies, decks,

or the like.

Another object is to produce an apparatus of the character outlined of strong, durable, simple, eflicient and inexpensive character; and in order that it may be fully understood,

referenceis to be had to the accompanyingy drawing, in which:

Figure 1 is a top plan view of a cooling tower embodying the invention.

Figure 2 is a section on the line II-II of Figure 1.

Figure 3 is an enlarged fragmental section through the louvered floor of the tower.

In the said drawing where like reference characters identify corresponding parts in all of the figures, 1 indicates a suitable pond or catch basin on the foundation of which are erected a series of spaced louver posts 2 and superposed louver posts 3, the superposed posts 3 adjacent their upper ends supporting a closed fence 4; for a purpose which will hereinafter appear. It will be Vunderstood that although a rectangular tower is illustrated,

the posts may be arranged in any suitable manner according to circumstances.

Below the solid or closed fence 4, the posts 3 and the upper ends of the posts 2 conjointly support a series of louvers 5, the undermost louver being formed with an extension portion 6 to insure discharge of water within the tower. Y y

Secured to the posts 2 on opposite sides of the basin 1 and spaced above the same, are

horizontal stringers 8, on which the outer ends of Va series of spaced troughs 9 `are received, said troughs inclining downwardly and inwardly and resting at their inner ends on horizontal girders or supports 10 carried by spaced posts 11 arranged in parallel rows 60 lon said stringers are battles 15 having their opposite edges overlapping adjacent troughs as illustrated in Figure 3, so that all water falling vertically or discharged from the undermost louvers shall fall either Von a baille and thence to a trough or directly into a trough, the troughs 9 and baiiies 15 thus conjointly providing a louvered floor.

Preferablyarranged centrally of the cooling tower is a vertical water supply pipe 16 75 for the supply of water to be cooled. The pipe 16 feeds a series of spray nozzles 17 suitably arranged within the space surrounded by the louvered fences and supported by branch pipe' 16a, each of said nozzles being 30 equipped with an air circulating vsleeve 19. The sleeves 19 arenot illustrated in detail as they form the subject-matter of a co-pending application.

In order to prevent a strong wind from 55 `blowing water out through the louvers 13 and also to form a balile or deflector to direct a draft of air upwardly through the louvered floor, a channel 20 is secured to each end post 2-3 in the longitudinal axis ofl the tower, 90 and to opposite sides of the water supply pipe 16. Slidingly received within said channels are a Vseries of boards or lbaiiies 21, the lowermost board resting upon the base 12 as shown in Figure 2, and being extended vertically to any desired height.

F roma consideration of the drawing in connection with the above description, it will be apparent that all water will be linally discharged by the troughs 9 intojthe central 100 1 agr* ywater passageway provided-between the twov Y sets'oflouvers 13 to the catch basin l, and I i y 'that by permitting the'a-irvto enter the bottom ofthe tower amore perfect contact of dry air by' the/ spraynozzla and.k waterjis insured thus more eiliciently evaporating and coollngthe water discharged f -Y Ingfoifder to Apry -erly bran-eel thev cooling tower, a series of cross girders 22 connect the oppositely disposed. posts 3.
